Managing direct mail campaigns for maximum response

By Pat McGrew

ZIP+4 In Action

Fenske Media, a Rapid City, South Dakota-based printer and direct-marketing solutions provider, offers a web-to-print solution that makes it easy to create and implement solicitation and giving campaigns. Over the last six years, Fenske has watched as response rates began to decline, despite its data acquisition and analysis. To reverse the trend, Fenske deployed a research methodology that used three types of data analysis to identify likely donors for the various fundraising campaigns it runs for clients:

• Factor analysis of the key variables touching socio-geodemographic indicators and integrating those results into the database to embellish the existing data.

• Cluster analysis to zero in on the groups that  actually exist in the database: What is the same about them? Do they share all characteristics or just some? Are they the characteristics you care about? Just because everyone in a cluster lives in an apartment building doesn’t necessarily mean you care about that aspect.

• Discriminant analysis to find the factors that separated responding clusters and non-responding clusters. There were the response drivers used to predict which prospects in which geographies had the highest probability of responding.

All three methods were deployed for each state to allow Fenske to better understand the dynamic nature of that market (factor analysis), the client groups who purchased goods and services in that market (cluster analysis) and the probability that each target in the database would be interested in direct solicitation (discriminant analysis).

That information was used with ZIP+4 postal information to identify new potential donors in a test. Each ZIP+4 postal code was converted to specific coordinates that allowed a broad set of external socio-geodemographic data to be merged with the existing data set. There were three mail drops. The first to test the direction of responses, the second to revise the model and capture more data on factors that impacted conversion and, finally, the third to provide a clearer predictive model.

Response rates for Fenske’s pre-analysis campaigns were under 0.5 percent. Actual test results showed a better than 2 percent response—more than enough to prove the value of the analysis.

Every direct mail campaign—whether it's a solicitation letter seeking new customers, offers for existing customers or a catalog full of products—should be managed for maximum response. However, in the rush to meet deadlines with limited resources, many organizations repeatedly choose to run the same campaigns knowing they're not getting the best response.
